Generating pseudo random numbers

You need to run some commands once (or on every /reload).

scoreboard objectives add random dummy
execute unless score seed random matches -2147483648.. run scoreboard players set seed random 731031
scoreboard players set mult random 1664525
scoreboard players set incr random 1013904223
scoreboard players set #16 random 16

Whenever you need a random output between 0 and a max number, you can call this function. It will store a random number from 0 (inclusive) to max (exclusive) in result random.

scoreboard players operation seed random *= mult random
scoreboard players operation seed random += incr random
scoreboard players operation result random = seed random
scoreboard players operation result random /= #16 random
scoreboard players operation result random %= max random

@logicguy1 That is actually not necessary since there are no players on the scoreboard objective.
